without disableOffline:true graphql operations failing with error in readFromStore

[attilah]

I've an AppSync application which is configured to use Cognito.

When I'm configuring the AppSyncClient without the disableOffline: true option I am ending up with this error upon executing any query:

  graphQLErrors: [],
  networkError:
   Error: Can't find field listKiosks on object undefined.

If was quite hard to figure out that disableOffline is needed to make this work.

I don't know what is the expected behavior:

1. Shall it work with offline capabilities in a node application (not necessarily from Lambda only)?

or

2. We could provide a better error message that under node this functionality is not available and if node environment detected, then bail out with a friendly error message during client initialization?

I ran into the same issue and came down to the same questions that you asked. Anyone here who can respond?

@stephankaag perhaps it was not clear, but specifying disableOffline: true works like a charm.

I know but I don't want disable offline functionalities.

Hi @attilah , @stephankaag

Are you using the sdk in Node.js/lambda ?

[stephankaag]

In my case next.js

This feels related to issue 102

@attilah this is a solution that works like a charm if you do not need offline capabilities...
